In 1808, Sir Humphry Davy invented the first electric light, revolutionizing technology. He demonstrated an arc lamp, using a battery to create an arc between two charcoal rods, which emitted bright light. Although initially too costly for widespread commercial use, Davy's innovation laid the groundwork for future advancements in electrical lighting. This pioneering work ultimately led to affordable lighting systems, transforming nighttime illumination in cities and homes and enhancing productivity.
